Protect your pickup truck’s invaluable cargo with the UnderCover® Triad—a premium, hard-folding truck bed cover featuring a robust aluminum panel construction, stealthy matte black finish, and effortless folding operation.

Undercover engineered the Triad as a sleek and innovative addition to your truck. The cover’s lightweight aluminum panels make operation a breeze, but don't let their light weight fool you. These panels are highly durable, significantly enhancing the security of your truck bed—they’re even capable of supporting up to 600 pounds of evenly distributed weight. A stealthy matte black coating finishes off the Triad, offering sleek styling and exceptional UV resistance.

Durability isn’t the UnderCover Triad’s only strong suit—it’s also highly weather-proof. Integrated EPDM rubber perimeter and corner seals help to protect your truck’s bed from the elements, keeping your cargo free from moisture, dirt, and other contaminants. What's more, dual hinge seals offer additional protection, preventing moisture intrusion at traditionally leak-prone seams.

Your truck’s bed is easily accessible thanks to the Triad’s easy-to-use tailgate clamps. Simply release the clamps, fold the cover toward the bulkhead, and secure it using the integrated straps, providing ⅔ bed access. Installing the UnderCover Triad is equally simple with its non-invasive clamp-on design.

  • Alluring matte-black smooth finish
  • EPDM rubber dual hinge seals, perimeter seals, and corner seals
